Finished the install with the only remaining item being the lower rear shock bolt. Does it require a washer? The stock shock doesn't require one since it has a built in plate on the lower mount and the washer from my old ASTs is too large and hits the shock body before the bolt is fully seated.

I did see in another thread that Thundermoose did not use a washer? Any other feedback?

If you find a washer let me know. I will say that mine has held up for last 2+ years without one.
